    My MBP is a month old and coconut is reporting that my battery is at 95% capacity. I calibrated 20 days ago and have been through 10 cycles. 95% isn't bad at all, but should I be concerned that the capacity will drop very quickly w/ time since its lost 5% in less than 5 weeks? Is this at all typical or is it a problem w/ coconut? Judging from other threads, most people get down to 95% in more like 5 months rather than 5 weeks.

    Yeah, I've had mine about three weeks and it is still over 100% according to coconut. Calibrated the first night i had it. I would think that to be down at 95% already would be a little much a little to fast.

    They don't always start out at exactly 100% after the initial calibration...some are a bit higher and some a bit lower. Has yours actually dropped or did it start at something less than 100%?

    This is actually the first time I've checked my capacity. I guess I'll start tracking it now and see if it drops another 5% in the next month. Anyone else noticing similar drops?

    ps, i leave my comp plugged in charger all the time, except for like 10 seconds when i move and sit in bed and have to unplug it from desk and plug it in here, and ive left comp on pretty much 24/7 since ive gotten it
